γ-Fe2O3@KSF: A recyclable catalyst for the efficient synthesis of pyrano-pyrimidinone derivatives
In this work, γ-Fe2O3@KSF as a stable heterogeneous and magnetic catalyst was prepared by the successive coating of γ-Fe2O3 shell on KSF core. The prepared reagent was characterized using different methods including FT-IR, XRD, TGA and SEM techniques and used for the one-pot synthesis of pyrano-pyrimidinone derivatives. All reactions were performed under mild conditions, during short reaction t...

متن کاملSilica-bonded n-propyldiethylenetriamine sulfamic acid as a recyclable solid acid catalyst for the synthesis of coumarin and biscoumarin derivatives
Silica-bonded n-propyldiethylenetriamine sulfamic acid (SBPDSA) was found as an efficient solid acid for the synthesis of coumarins. Coumarin derivatives were obtained via the Pechmann condensation reaction of phenols and β-keto-esters at 80 oC under solvent-free conditions. Also, biscoumarins were obtained via the condensation of aldehydes and 4-hydroxycoumarin in water at reflux conditions. T...
